What is a vaccination doctor and how does it work?
Well, the first vaccination was created by Edward Jenner, who found that milk maids did not get smallpox even thought the cows they were milking had cowpox.
The cowpox disease was not at all deadly, but had similar properties to the small pox disease, which had no cure at the time. I think that if you have been exposed to a little bit of the virus, then maybe you will learn how to fight smallpox!
I decided to gather three things to prove my findings: Small pox from a victim, Cow pox from a cow and someone to test my theory on. I will test on James Phipps, the gardener's son.
I can't believe it worked! We injected cowpox into me and after a few months, we we injected small pox and I'm not sick!
Yes! my prediction are right! I even tried this on other children and the same results came! I am so happy to know we have finally killed such a deadly plague. however, I am not too sure how exactly I did this!
So now we know that when we are given part or a dead cell, our body can learn how to best defend itself against it so we will not be affected once the illness attacks
How does the body know how to defend itself before the imposters come?
The body creates copies of the cell and then studies how to defend itself by looking at other previous attacks from other illnesses.
